PURPOSE: A hot water heat exchanger for a boiler is provided to improve heat exchange efficiency by reducing the temperature degradation by the heat exchange of hot water. CONSTITUTION: A hot water heat exchanger for a boiler comprises: a top finishing plate; a heating water inlet(201) wherein heating water which is heated by a boiler is flown in; a heating water outlet(202) which water is heated up by heat-exchanging and returns to a pipe of the boiler through; a hot water outlet(204) which discharges the hot water which is heated with the heating water; heat exchange plates(210,220) which include concave parts(211) which are formed in the upper side of the even numbered turns of the second heat exchange plate and convex parts(212); heating water flow channels; and a water flow channel. A plane part is formed between the concave parts. A plurality of the protrusions which decentralizes the flow of the fluid is formed on the planar section. |
